IMPROVEMENT IN GANG-SAW MILLS.l

Specification forming part of Letters Patent No. 212.526, dated February 18, 1879; application filed December 4, 1878.

To all whom it may concern:

Be it known that we, H. D. WicKEs and E. N. WIGKES, of East Saginaw, in the county of Saginaw and State of Michigan, have invented an Improvement in Gang-Saw Mills,

of which the following is a specification The nature of our invention relates to new and useful improvements in that class of sawmills known as gang-mills57 and the invention consists in the peculiar construction ofthe frame, by means of which greater stability to the general structure is admits of securing the base of the frame upon timbers independent from those ordinarily employed for supporting the main pillow-blocks and crank-shaft, thereby destroying the connecting vibrations produced from the heavy labor upon the main shaft which is sure to follow where the gang-frame, pillow-block, and main shaft rest upon the same base.

The invention also consists in the new construction and combination of parts necessary to these beneficial results, and as more fully hereinafter described.

In the drawings, Figure 1 is a perspective view of our improved `gang-saw mill. Fig. 2 is a front elevation of the same.

ln the accompanying drawings, which form a part of this specification, A A represent the vertical cheeks, between which the gang-saws have their reciprocating movement in guides of the usual construction. These cheeks are provided with shoulders a, which rest upon shoulders b b of thebase, and .to which they are rigidly secured. The vertical sections c of the cheeks, to which the lower guides are attached, project downward below the point of intersection between the upper and lower parts of the frame.

B B form the lower part of theframe, their upper ends being rigidly secured to and coincident with the shoulders upon the upper part of the frame; but these parts B B are spread obtained, and which apart at their feet to give greater stability to the structure, and to avoid the necessity, as occurs in gang-mills of ordinary construction, of being supported upon the same timbers which carry the pillow-block Z and main dri ing-shaft h. C G are the timbers upon which rests t-he improved gang-sawmill frame. l) is the timber which supports the pillow-block and main shaft, which is subject to great vibrations, produced by the heavy labor required ofthe main shaft.

In practice, it is found that when the whole of the gang-saw-mill frame is in vertical lines one of the legs of said frame must rest upon the timbers D. When so resting the vibratory strain caused by the severe labor of the main shaft is communicated to the gang-frame, to the serious detriment of its perfect andsuccessful operation.

By the construction herein described we are enabled to provide separate and independent foundations for the gang-saw frame, and for the pillow-block and shaft, so that the vibrations of the one will not affect the successful and perfect operations of the other.

What we claim as our invention, and desire to secure by Letters Patent, is-

The frame for gang-saw mills described, consisting of the spreading base-frames B B, having forked upper ends, terminating in bearing-faces b b, and the parallel cheeks A A, provided with sections C, carrying the lower guides and projectin g down between the forked ends of the base-frames, said cheeks having shoulders c, which rest upon and are secured to the bearing-faces b b, constructed and arranged substantially as and for the vpurposes set forth.
